## Hodges-Lehman estimator of location

### Description

Calculates the Hodges-Lehman estimate of location –which is consistent for the true pseudomedian– using Walsh averages (Hollander and Wolfe 1999, pgs. 51-55). If requested, the function also provides confidence intervals for the true pseudomedian. In a symmetric distribution the mean, median, and pseudomedian will be identical.

### Usage

`HL.mean(x, conf = NULL, method = "exact")`

### Arguments

`x` |
A vector of quantitative data. |

`conf` |
A proportion specifying 1 - |

`method` |
method for confidence interval calculation. One of |
